IMPROVEMENT 1N PLAITEE ron SEWING-MACHINES.

ToALL WHOM 1r MAY C'ONCEEN: l d y y Be it known that we, Hacia CAwL, DoUcLss Cdnnmmand Janes WrWuEELEa, ofthe city of Troy, county of Rensselaer, and State of New York, have invented anew and iinproved Plaiter," for folding plaits inil-inen' and cotton or oth-er cloth; and we 1o. licreby declare thatr'tihe following is a full ,rtrnc,.and e-:taet desciiption of thesame, reference being herebyh'ad to the accompanying drawings,.whiehfruakc and, form apart ot this specification., j t '-f Like lett-ers represent and refer to like or corresponding pairs.'

Figure-1 of the accompanying drawingsis a Cperspectivcviewcfia:plaiter containing-our saidin-vention,v 4

showing the various parts thereof, each being ,more fully hereinafter described and set forthi l Figure 2 is a longitudinal section of thelplaiter-,shown'a't iig.1.more clearly, showing the construction'andl combining ofthe various parts thereof, substantially us hereihafte'xfdescribcd anil'sct forth.`

Our invention relates' to plaiter's'which are-attached to'sewingmachincs,` for'the purpose of laying or foldingI plaits in linen or cotton cl'otlrpreparatoryto stitchingvthe sameewith the vinachinc, andl consists in the employ-A ment of a gauge or guide, Dfor.the purpose of fixing the widthof the'irst plaitto be laid and stitched in any strip of cloth, and` for guiding tli-e'cloth through the plat'cr while such first plaitisbcingstitchcd n s aforsaid,

substantiallyas hereinafter described and setforth. i

It also dousistsl in the employment of the additional blnde'orgziuge E,-aftert'he. first plait has been stitched,

to be placeduuder eachplait and anainst the row of stitching through the same, to 'guidethe clotliandjbnthe width ofthe next plait, substantially as hereinafter fullyV described and s et forth To Venable others skilled in the art to which `our invention relates to make and use the same, we will here `proceed to describe the construction and operation of the saine, which is as follows, to witz' l A, figs.' l and 2, is a. stationary blade or plate. B, same figures', is an adjustable' plate' or blade, placca a little above 'and'parallel with thesaid plate with asp'ace'bet-wcen for therrcceptionof the cloth.' i Said plate B is adjustable by means of the slots and lsmall screwsjf C iS tllldaljlmble-Pll, 0.n the Oplsitende? v the plaiter, and a little above said plate B, the end of which is 'between said plates and C." 1 Said plate C' adjustable by means of the slots and small screws y g. VAI) is'an adjustable gaugc, regulated by tho'thumb-screw .V

h, and E is an additional blade4 or gauge, also movable, and-regulated by theth'uuilrscrew c.

In the use of this plaiter, the blades B and C are first .ailju'sted by means of the screws and g, so -as to' make the plait of the desired ividth.- A strip of cloth is pla'ccd inthe space'bet-wcen the blades A'and B, and the side to be pliiited is folded over the end Of-'thc blade B, and-in thc opposite direction over the end of the blade C. The gauge D is thenadjusted liyineans o f thcithunib-screw IL to the desired width of-theirst plait..-

The cloth is then placed so that its edges rest against said; gauge, which 'guides the'cloth as itfpasses through the plater andyis stitched by the sewing-machine. By this means-thc first plait will beof a uniform width throughout its whole length, After the first plait is thus folded andV stitched, it is again placed in the plaiter as beforc,'but in such a manner as to fold a second plait by means ot'- thc bladesnand -The additional blade: o r gauge E is then advanced so that its edge enters under the folded edge ofthe first. plait, and restfagainst the seam. The sewing-,machine is then 'put in motion, and as the cloth is drawn by thcfeed through the plaiter,\

said gauge E resting against the previous seam, :is afbresaid, guides the cloth, ami causes the second plait tobe of an exact and uniform. widtlrthroughout. lter stitching thesocond plaittthe said gauge is placed under the sameand against the seam, and so with any number of plait-s as they are suecessivelylaid'and stitched."

The various devices connected and combined together, 'and forming the plaiter hereinbcfore described, may be of anysze and strength. deemed best, and may be made of brass or any other material 'that will answer the required purpose, and can be attached to any sewing-machine without material trouble or expense. 4

Having thus described the nature of our said, invention and' improvements, what we claimlns'onr invention, and'desire to secure by Letters Patent 'of the United States,`.is

The'plates A, B, and C, and the gauge l), for the purpose ot'. guiding the cloth as 'it passes lthrough they plaiter and reo D any in the manner and for the purposes herein dcscribedand set forth. K l l In testimony whereof, wc have hereunto sc`t our hands, this 29th day Septciub'crrAf Daltlti.`
